The first 2x when a magazine is loaded on a phone or tablet, an "add this magazine to your homescreen button" appears. Just click the icon below the button and follow the onscreen instructions. Once completed an "app" button for that magazine will be put on your device. This option only appears the first two times you open the magazine (so we don't annoy you). If you miss those, you will need to clear your browser's data/cache in order to get it to appear again.
Note: This function only works with a devices native browser....Safari for Apple and Chrome for Android.
